DR331-105BE Description

Short technical summary and product information.

The Bourns DR331-105BE is a surface mount common mode choke from the DR331 series, featuring a bifilar winding design. It provides 1 mH ±25% inductance when measured at 100 kHz and 0.1 Vrms. The component has a maximum DC resistance of 400 mOhm and a rated current of 500 mA. The voltage rating is 42 VAC / 80 VDC. It is designed for the suppression of EMI in data and signal lines, operating over a wide frequency range up to 1000 MHz.

 

The choke is housed in a horizontal, 4 flat lead surface mount package with dimensions of 7.30 mm length, 5.40 mm width, and 5.00 mm maximum height. Lead spacing is 2.54 mm. It operates over a temperature range of -40°C to 135°C and has a maximum temperature rise of 30°C at rated current. The storage temperature range is -55°C to 135°C.

 

This component is RoHS3 compliant and has an MSL rating of 1 (unlimited). It is suitable for use in automotive, industrial, and consumer electronics where common mode noise filtering is required.
