The Schaffner RN142-1.4-02-27M is part of the RN series of current-compensated common mode chokes. These chokes are designed to attenuate common-mode or asymmetric interference signals in AC powerline inputs, often used in conjunction with suppression capacitors.
Key electrical specifications include an operating voltage of 300 VAC, an operating frequency range from DC to 400 Hz, and a rated inductance of 27 mH at 10 kHz. The choke has a maximum current rating of 1.4A and a DC resistance of 500mOhm typical. It also features a low inductance reduction of less than 10% under DC bias at 25°C.
This component operates within a temperature range of -40°C to 100°C and has a high potential test voltage of 1500 VAC winding-to-winding and 4000 VAC winding-to-housing. The housing and potting compound are rated UL 94V-0 for flammability.
The RN142-1.4-02-27M is designed for through-hole mounting with a horizontal, 4 PC pin package. Its dimensions are 33.10mm in length and 32.50mm in width, with a maximum height of 20.00mm. This dual-choke configuration is suitable for switch-mode power applications and EMI input filters.
