Electromagnetic AC Compressor Clutch Coil 12V 100mm OD Honda Civic CR-V OEM 38900-RNA-A01

The Silk TCC-38900-DB electromagnetic AC compressor clutch coil is a precision-manufactured replacement component engineered for Honda and Acura vehicles equipped with Denso and Sanden compressor assemblies. Wound from 99.9% pure electrolytic copper wire with automated CNC layer-winding technology and encapsulated in Class H high-temperature epoxy, this 12V DC coil generates uniform magnetic flux across the entire clutch engagement surface for smooth, chatter-free compressor operation. The 100mm outer diameter zinc-plated steel housing provides robust structural integrity and excellent corrosion resistance, while the precision-machined 60mm inner bore and 45mm assembly diameter guarantee exact alignment with the compressor nose cone without shimming. Every TCC-38900-DB undergoes 100% in-line electrical testing including resistance verification, 1500V AC dielectric withstand testing, and magnetic flux mapping before packaging, with serialized test records maintained for complete batch traceability. For import specialist repair shops, Honda dealership service departments, and aftermarket parts distributors, this clutch coil delivers the electrical precision and mechanical durability required for professional-grade compressor overhaul and clutch rebuild services.

• Electromagnetic Precision Engineering: The coil is wound with precisely tensioned 99.9% pure electrolytic copper wire in uniform, tightly-packed layers using CNC winding machines, ensuring consistent magnetic flux density of at least 0.8 Tesla at the engagement surface for reliable, slip-free clutch lockup under all operating conditions.
• Class H High-Temperature Encapsulation: The entire winding assembly is vacuum-impregnated and encapsulated with Class H (180°C rated) epoxy resin compound, providing complete protection against thermal degradation, moisture absorption, chemical contamination, and vibration-induced insulation breakdown throughout the coil service life.
• Direct-Fit Honda Acura Compatibility: Engineered to precisely replace OEM part numbers 38900-RNA-A01, 38900-RNA-A02, and 38900-PNB-A01, with exact dimensional matching including 100mm OD, 60mm ID, 32mm thickness, and 45mm assembly diameter for guaranteed bolt-on installation without modification.
• Zinc-Plated Steel Housing Durability: The outer coil housing is precision-stamped from deep-drawn low-carbon steel and finished with a bright zinc electroplate coating that provides long-term protection against rust, galvanic corrosion, and underhood chemical exposure in all climate zones and operating environments.
• Tight Resistance Tolerance Control: Each coil maintains a precisely controlled resistance of 3.0 to 3.6 Ohm with ±0.2 Ohm tolerance, ensuring consistent electromagnetic pull-in characteristics and predictable current draw that protects the vehicle AC clutch relay and electrical system from overload conditions.
• Wide Platform Coverage: One SKU covers Honda Civic (2001-2011), CR-V (2002-2011), Element (2003-2011), Accord (2003-2007 2.4L), Acura RSX (2002-2006), and Acura TSX (2004-2008), dramatically reducing inventory complexity for distributors serving the Honda vehicle aftermarket.
• 100% Production Electrical Testing: Every coil is individually tested for DC resistance, insulation dielectric withstand at 1500V AC, inductance value, and magnetic flux distribution mapping to verify uniform field strength and detect any winding anomalies before shipment.

The TCC-38900-DB electromagnetic clutch coil is purpose-engineered for Honda and Acura vehicles equipped with Denso 10PA-series, 10S-series, and Sanden SD-series AC compressor assemblies across multiple popular model platforms. Primary Honda applications include Civic (EM2, ES1, EP3, FA1, FG1 chassis, model years 2001 through 2011 covering 1.7L D17, 2.0L K20, and 1.8L R18 engine configurations), CR-V (RD4-RD7, RE1-RE4 chassis, 2002 through 2011 with 2.4L K24 engines), Element (YH1-YH2 chassis, 2003 through 2011), and Accord (CM4-CM6 chassis, 2003 through 2007 2.4L K24 variants). Acura applications cover RSX (DC5 chassis, 2002 through 2006) and TSX (CL9 chassis, 2004 through 2008). The coil is also compatible with select Honda Stream and FR-V models that share the same K-series engine platform and Denso AC compressor architecture. Cross-reference OEM part numbers include 38900-RNA-A01, 38900-RNA-A02, 38900-PNB-A01, 38900-RAA-A01, and 38900-PZD-A01. This coil is ideal for professional automotive workshops specializing in Honda and Acura vehicle service, independent AC specialty shops performing compressor disassembly and clutch mechanism overhaul, and fleet operations requiring reliable replacement components for high-mileage vehicles in continuous service. Its pure copper construction and Class H insulation system ensure consistent electromagnetic performance and extended service life even under the severe duty cycles typical of delivery vehicles, ride-share fleets, and commercial transport applications. Always verify fitment using the vehicle VIN and existing OEM compressor part number before ordering to ensure correct application compatibility.

Every TCC-38900-DB electromagnetic AC compressor clutch coil is individually packaged in a custom-fitted foam-lined carton box with die-cut cushioning that immobilizes the coil and protects the winding housing, electrical connector, and mounting surfaces from transit-related impact damage. The coil is first vacuum-sealed in an anti-static polyethylene bag with a silica gel desiccant sachet to maintain internal dryness and prevent terminal oxidation or corrosion during extended shelf storage, then placed into the protective inner carton. Each box features a product identification label with OE cross-reference numbers, batch traceability code, manufacturing date, coil resistance test value, and QR code for full supply chain visibility and inventory management. Standard packaging is neutral with the option for custom-branded retail boxes featuring your company logo, custom part numbering system, and multilingual product information for global distribution markets. Our quality management system operates under ISO 9001:2015 certification, and all electromagnetic coil products carry CE and RoHS compliance documentation. Every coil undergoes 100% in-line electrical testing including DC resistance measurement, 1500V AC insulation dielectric withstand verification, inductance measurement, and magnetic flux distribution mapping to confirm uniform electromagnetic field characteristics. A comprehensive 12-month warranty against manufacturing defects applies from the date of shipment, with extended warranty terms available for volume contract and fleet supply customers. Shipments of 500 pieces or more benefit from consolidated pallet shipping with reinforced edge protectors, moisture-barrier stretch wrap, and fumigated ISPM-15 compliant wooden pallets to ensure cargo integrity throughout international ocean and air freight logistics chains.
