Notes:
For “D12” and “D24” models the
case is connected to pin 2 (–Input).
For “D48” models, the case is
connected to pin 1 (+Input).
Optional Functions
BWR 33 Watt DC/DC’s are designed with an On/Off Control
function with positive polarity in the pin 4 position.
L1 Pin length: 0.110 in. (2.79mm) ±0.010
L2 Pin length: 0.145 in. (3.68mm) ±0.010
Pin length options require a minimum order quantity.

➀
PART NUMBER STRUCTURE
MECHANICAL SPECIFICATIONS
➀ Typical at TA = +25°C under nominal line voltage and balanced “full-load” conditions (5V @ 3.3A/3.3V @ 5A).
➁ Any combination of 5V/3.3V rated I
OUT current, not to exceed 33 Watts of output power. (See derating graphs.)
➂ Ripple/Noise (R/N) measured over a 20MHz bandwidth. All models are specifi ed with 1µF ceramic output capacitors.
➃ Tested from 10% load to 100% load (other output at 10% load).
➄ Nominal line voltage, no load/balanced full-power condition.
➅ Tested from no-load to 100% load (other output at no-load).
➆ Output trim may impact 5V load regulation.
