PACKAGING CODE

Packaging Code Description

SP2 50 piece sample
TR1 Standard Package:(This is an insert)

1000 pieces of fuses on 12mm tape-and-reel on a 7 inch (177mm) reel per EIA Standard 481

Description

• The first and most reliable surface mount telecom circuit

protector designed to protect against power cross faults
and comply with all surge requirements.

• Allows compliance with telecom regulatory standards

including Bellcore GR 1089, UL 1950/60950, and FCC part

68. Application circuit testing is recommended.

• Eliminates the need for a current limiting resistor.

• Protects against overcurrent conditions found in telecom tip

and ring applications.

• RoHS Compliant version available (-R option)

* If the device does not open at 250% within 120 seconds, increase

current to 300% of amp rating.Device must open in 10 seconds max.
