Product details

Press-Fit and Solder Termination for Reflow-Friendly Assembly

The B24B-KRWHK-C(LF)(SN): This header uses a hybrid press-fit and solder termination. The press-fit tails hold the component in place during wave or selective solder reflow, preventing skew from board handling. The 3.40 mm post length provides enough stand-off for the solder fillet to form without wicking into the contact interface. The through-hole mounting style with square male pins mates with standard KRW series crimp receptacles.

The B24B-KRWHK-C(LF)(SN) sits at 24 positions — the B22B-KRWHK-C(LF)(SN) (22 positions) and B28B-KRWHK-C(LF)(SN) (28 positions) are direct siblings with identical electrical ratings and material specs. The choice is purely the circuit count needed on the BOM.
