Allen-Bradley 80025-523-10-R Capacitor 0.1uF 3700VDC

Allen-Bradley 80025-523-10-R is an NCL snubber capacitor rated at 0.1 µF with a 3,700 V DC rating, designed to suppress transient energy in high‑voltage power electronics such as thyristor blocks and inverter modules. This film capacitor is used in snubber networks to damp dv/dt transients and protect switching devices, helping prevent arcing and voltage spikes in industrial drives, power supplies, and motor controllers. It specifies ±5% tolerance and a 3,700 V DC rating, with peak voltage around 5,500 V and a surge capability near 7,200 V in typical listings for this model. As of December 13, 2018, Allen-Bradley discontinued the 80025-523-10-R, so current sourcing typically occurs through surplus, repair, or legacy channels for Rockwell Automation installations. In practice, distributors commonly list this part as a legacy snubber capacitor used in older Rockwell automation assemblies, and buyers often verify compatibility with cross-reference data or consider modern equivalents that meet or exceed the original 0.1 µF, 3,700 VDC rating.
