COMPLIANT

TRADITIONAL

Pb

*Add “LF” suffix for RoHS requirement. Example: SM3-100GLF

Gowanda designates a component RoHS-compliant by adding “LF” (lead free) to the part number.  
These LF components meet the ≤ .1% lead requirement and they are compatible with 260°C soldering processes.

NOTES:

• Operating Temperature Range:

-55°C to +125°C

• Current Rating is based on a 35°C temperature 

rise at an ambient temperature of 90°C

• Epoxy-encapsulated for environmental 

protection and superior strength to withstand all 

types of reflow soldering

TAPE AND REEL SPECS:

Pcs./Reel maximum: 

2000

Pitch between parts: 

8 mm

Tape width: 

8 mm

Reel diameter:
