Features, Applications

Description

This 100% Lead-free, RoHS compliant and Halogen-free fuse series has been designed specifically to provide over current protection to circuits that see high working ambient temperatures (up to 150C). The general design ensures excellent temperature stability and performance reliability. In addition to this, the high It values typical of the Littelfuse Ceramic Fuse family ensure high inrush current withstand capability. Features Agency Approvals

Notes: 1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting Rating tested at rated voltage with time constant < 0.8 msec. 2.Nominal Resistance measured with < 10% rated current. 3.Contact Littelfuse if application transient surges are less than 1 ms. 4.Nominal Voltage Drop measured at rated current after temperature has stabilized. 2016 Littelfuse, Inc. Specifications are subject to change without notice. Application testing is strongly recommended. Revised: 10/25/16

Devices designed to carry rated current for 4 hours minimum. It is recommended that devices be operated continuously at no more than 80% rated current. See "Temperature Re-rating Curve"for additional re-rating information. Devices designed to be mounted with marking code facing up.

Note: 1. Re-rating depicted in this curve is in addition to the standard re-rating of 20% for continuous operation. Example: For continuous operation at 75 degrees celsius, the fuse should be rerated as follows: = (0.68)IRAT
