209 Series - 2AG Slo-Blo®(Time-Lag) Lead-Free Subminiature Glass Body Fuse

Littelfuse 209 Series 350V time-lag (Slo-Blo) fuses are available in cartridge form or with axial leads. This series provides the same performance characteristics as its 3AG counterpart, while occupying one-third the space. Sleeved fuses are available.

Features:

In accordance with Underwriter’s Laboratories Standard UL 248-14
Fuses are coard washable in most solvents
Available in cartridge and axial lead form and with various forming dimensions
RoHS compliant and lead free

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)	0.5
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)	350
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 (A^{2^sec)}	1.16
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
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)	0.688
Close Info	Interrupt Rating	100A@350VAC
Package Size/Form Factor Close Info	Package Size	2AG (5x15mm)
Close Info	Terminal Strength	Contact Littelfuse
Thermal Shock Close Info	Thermal Shock	MIL-STD-202G Method 107G Condition B
Terminations Close Info	Terminations	Bright nickel plated brass
Operating Temperature (deg C) Close Info	Operating Temperature (deg C)	-55
Moisture Sensitivity Level Close Info	Moisture Sensitivity Level	Contact Littelfuse
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	MX
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	Glass Body(borosilicate)
Close Info	Thermal Shock	MIL-STD-202G Method 107G Condition B
Humidity Close Info	Humidity	MIL-STD-202G Method 103B Condition A
Close Info		MIL-STD-202G Method 101E, Test Condition B
Close Info	Element Cover Coat	Conformal Coating
