Miniature Aluminum Electrolytic Capacitors Nichicon UHE2A121MHD6 Low Impedance High Reliability Radial Lead
UHE Series Miniature Aluminum Electrolytic Capacitors
The UHE series capacitors are miniature-sized, low-impedance, and high-reliability aluminum electrolytic capacitors designed for demanding applications. They offer extended operational life, withstanding up to 4000 to 10000 hours of operation. These capacitors are compliant with the RoHS directive (2011/65/EU, (EU)2015/863) and have been approved by the Reliability Center for Electronic Component, Japan (Certification No. RCJ-03-23C). Ideal for use where space is limited and high performance is required.
