SRN4012BTA & SRN4018BTA Semi-Shielded Inductors

Bourns SRN4012BTA and SRN4018BTA Semi-Shielded Power Inductors are designed with a semi-shielded construction and bottom-soldered lead-wire for enhanced product reliability. These inductors are AEC-Q200 compliant and operate in a temperature range of -55°C to +125°C. The SRN4012BTA series offers 4mm x 4mm x 1mm dimensions, and the SRN4018BTA series has 4mm x 4mm x 1.6mm dimensions. Bourns SRN4012BTA and SRN4018BTA Semi-Shielded Power Inductors are RoHS compliant and halogen free. Both variants are well-suited for applications where higher inductor reliability may be required. Typical applications include automotive systems, lighting, power supplies, consumer and telecom electronics, DC-DC converters, and industrial.
