About the Bourns Inc. SRP4020 Series

The Bourns Inc. SRP4020 Series series groups 46 related part numbers, each listed with full specifications, a datasheet where available, and an RFQ option. The listed variants share a common case of Nonstandard, inductance frequency - test of 100 kHz and mounting of Surface Mount. Variants differ by current - saturation, DC resistance and frequency - self resonant, so you can match the exact current - saturation your application requires using the selection guide below. The range mixes active and legacy part numbers, so you can source both current Bourns Inc. SRP4020 Series variants and discontinued ones from a single page.
