3403.0157.11 Description

Short technical summary and product information.

The Schurter 3403.0157.11 is a surface mount board mount fuse from the UMT 250 series. It is rated for a continuous current of 125 mA at 250 VAC and 125 VDC. The fuse features a Time-Lag T (slow blow) response characteristic suitable for pulse-shaped continuous currents.

 

This fuse offers a high breaking capacity of 200 A at 250 VAC (IEC) and 35 A at 125 VDC. Housed in a compact ceramic body with tin-plated copper alloy terminals, it measures 10.10 mm x 3.00 mm x 3.00 mm in a 2-SMD square end block package. The operating temperature range is -55°C to 125°C with MSL 1 moisture sensitivity.

 

Approved by CQC, cURus, KC, and VDE, the 3403.0157.11 is designed for primary protection on SMD PCBs, medical equipment, and battery protection applications. It is impermeable to potting compound for use in intrinsically safe applications per ATEx and IECEx requirements.
