160kΩ 0.5W High Power Thick Film Chip Resistor with ±1% Tolerance for Industrial Applications

CRH1206F160KP05Z is the 160kΩ grade of EVER OHMS' CRH high-power thick film chip resistor family, commonly referred to as a 1206 160K 0.5W EVER OHMS resistor. It doubles the power rating of a standard 1206 thick film part (0.25W) within the same 3216 metric footprint, while keeping ±1% tolerance and a −55℃ to +155℃ operating range. Typical uses include feedback dividers, bus bleeder networks, snubber branches and bias/sense paths.

Part number decoding: CRH = high power thick film series; 1206 = imperial size (3216 metric); F = ±1% tolerance (J would be ±5%); 160K = 160,000Ω; P05 = 0.5W (500mW) at 70℃; Z = taping/lead-free suffix per factory datasheet.

Key specifications: rated resistance 160kΩ ±1% (158.4kΩ–161.6kΩ); rated power 0.5W at 70℃ ambient; maximum working voltage 200V, short-time overload 400V (approx. 5s); TCR typically ±100ppm/℃ in this resistance range; insulation resistance ≥10GΩ; dimensions 3.05±0.10 × 1.60±0.20 × 0.55±0.15 mm; 96% alumina substrate with ruthenium-based thick film element, glass glaze protection, Ni barrier plus lead-free Sn outer termination; supplied on 5,000pcs/reel tape and reflow/wave solder compatible.

Design notes. Thermal limit would allow √(0.5×160000) ≈ 283V, but the 200V package voltage limit governs first — at 200V the dissipation is only 0.25W. Maximum continuous current is √(0.5/160000) ≈ 1.77mA. For a 400V bus, a single 160kΩ part dissipates 1W, so series connection is required: two in series put each part at its 200V limit, while three in series (480kΩ total) leave each at roughly 0.11W and 133V. Derate linearly above 70℃ — about 0.41W at 85℃, 0.29W at 105℃ and 0.18W at 125℃ — and keep a 1.5–2× margin in enclosed enclosures.

Sourcing. Shenzhen Shunhai Technology Co., Ltd. is an authorized mainland China distributor for EVER OHMS, supplying genuine CRH1206F160KP05Z with sample-to-production support, alternative matching and lead-time confirmation. Huanian Mall, Shunhai's online procurement platform, offers model search, live stock and tiered pricing for quick quotation and small-volume replenishment. Confirm tolerance, packaging (full reel vs. loose) and whether original datasheet and environmental reports are required before ordering.
