465 Series - NANO^2® 250V UMF Time Lag Miniature Fuse

The Surface Mount Nano² 250V UMF product family complies with IEC Publication IEC 60127-4-Universal Modular Fuse-Links [UMF]. This IEC standard has been accepted by UL/CSA making it the first global fuse standard.
The Nano² 250V UMF fuse family is based on the proven NANO² fuse product technology.
Product is compatible with lead free solders and higher temperature profiles.
RoHS Compliant

Electrical Characteristics

Help	Property	Value
It is established by Littelfuse as a value of current which the fuse, fuseholder, fuse clip or other fuse accessory can carry, based on a controlled set of test conditions. Close Info	Ampere Rating (A)	4
The maximum rms AC voltage and/or the maximum DC voltage at which the fuse is designed to operate. For example, fuses rated at 600 volts and below may be applied at any voltage less than their rating. There is no rule for applying AC fuses in DC circuits such as applying the fuse at half its AC voltage rating. Fuses used on DC circuits must have DC ratings. Close Info	VAC (V)	250
Refers to how rapidly the fuse responds to various current overloads. Fuse characteristics can be classified into three general categories: very fast-acting, fast-acting or Slo-Blo® (time delay)fuse. The distinguishing feature of Slo-Blo fuses is that these fuses have additional thermal inertia (surge withstand) designed to tolerate normal initial or start-up overload pulse. Close Info	Opening	Slo-Blo®/Time Lag (T)/Time Delay
Package Size/Form Factor Close Info	Package Size	12.1 x 4.5mm
RMS Surge (Non-repetitive) On-state Fusing Current- Measure of let-through energy in terms of current and time for fusing purposes. Close Info	Nominal Melting I²T (A²sec)	48.4
Cold resistance is the resistance obtained using a measuring current of no more than 10% of the fuse's nominal rated current. The factory should be consulted if this parameter is critical to the design in question. Close Info	Nominal Cold Resistance (Ohms)	0.016
Close Info	Interrupt Rating	100A@250VAC
The part of a fuse enclosing the fuse elements and supporting the contacts. Body is also referred to as cartridge, tube, or case. Close Info	Body	Ceramic
Color or Alpha-Numeric code used to define the amp rating of the device for ease-of-maintenance and quality checks. Close Info	Marking Code	LF T4AL AC 250V
Moisture Sensitivity Level Close Info	Moisture Sensitivity Level	TBD
Operating Temperature (deg C) Close Info	Operating Temperature (deg C)	-55�C - + 125�C
