1277AS-H-1R0M=P2 Description

Short technical summary and product information.

The Murata 1277AS-H-1R0M=P2 is a fixed inductor featuring a shielded wirewound drum core construction with an iron powder core. It offers an inductance of 1 µH with a tolerance of ±20% and a continuous current rating of 3.1 A. The maximum DC resistance is 45 mOhm, ensuring low power dissipation. The operating temperature range spans from -40°C to 85°C, making it suitable for a wide variety of environments.

 

This inductor is housed in a 1210 (3225 Metric) surface mount package with dimensions of 3.20 mm x 2.50 mm x 1.20 mm. The compact footprint and low profile enable use in space-constrained designs. The shielded construction minimizes electromagnetic interference, improving performance in sensitive circuits.

 

Typical applications include power supply filtering, DC-DC converter output stages, and noise suppression in portable electronics. The part is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified. No datasheet is currently linked, and the manufacturer page is inaccessible.
