➀ Please refer to the model number structure for additional ordering part numbers and options.

➁ All specifications are typical unless noted. General conditions for Specifications are +25 deg.C,

Vin=nominal, Vout=nominal (no trim installed), full rated load. Adequate airflow must be supplied

for extended testing under power.

All models are tested and specified with external 1μF and 10 μF paralleled output capacitors and

no external input capacitor. All capacitors are low ESR types. Caps are layout dependent. These

capacitors are necessary to accommodate our test equipment and may not be required in your

applications. All models are stable and regulate within spec under no-load conditions.

➂ Some models are pending safety certification.

H

Conformal coating (optional)

Blank = no coating, standard

H = Coating added, optional, special quantity order

C

-

RoHS Hazardous Materials compliance

C = RoHS6 (does not claim EU RoHS exemption 7b–lead in solder), standard

Y = RoHS5 (with lead), optional, special quantity order

Note: Some model combinations may not be

available. Contact Murata Power Solutions for

availability.

N

On/Off Control Polarity

N = Negative polarity, standard

P = Positive polarity, optional

B

Baseplate (optional, not available on UEE-3.3/15-D48 models or SMT models)

Blank = No baseplate, standard

B = Baseplate installed, optional, special quantity order

Lx

Pin Length Option (Through-hole packages only)

Blank = Standard pin length 0.180 inches (4.6mm)

L1 = Pin length 0.110 inches (2.79mm)*

L2 = Pin length 0.145 inches (3.68mm)*

* Special quantity order is required.

M

Surface Mount (SMT models cannot accept the baseplate)

Blank = Thru-hole pin mount, no SMT

M = Surface mount (*MSL Rating 2a, no baseplate allowed)

*Reflow temp ≤ 250°C
