RL187-102J-RC is a radial lead RF choke from the RL187 Series designed for power supply and DC/DC converter applications. This component features an inductance of 1000 µH with a tolerance of ±5%, a minimum Q factor of 90 at 252 kHz test frequency, and a self-resonant frequency (SRF) of 1.3 MHz. The choke has a DC resistance (DCR) of 6.0 O and supports a DC current rating of 150 mA, making it suitable for output filtering in switching power supplies, desktop notebooks, and DC/DC converters. Its high Q characteristic and RoHS compliance ensure efficient energy storage and environmental compliance in modern power management circuits.
