2AG Slo-Blo Fuse 229/230/290/291 Series
The 2AG Slo-Blo® fuses are available in cartridge form or with axial
leads. Axial leaded fuses are board washable. 2AG fuses provide the
same performance characteristics as their 3AG counterpart, while
occupying one-third the space. Sleeved fuses are available.

2AG Indicating Slo-Blo Type Fuse
The 2AG Indicating Slo-Blo® fuse instantly identifies itself upon
opening by showing a discoloration of its glass body. Guesswork
and time consuming circuit testing are eliminated. This unique
design offers the same quality performance characteristics as
the standard 2AG fuse design.
ENVIRONMENTAL SPECIFICATIONS:
Operating Temperature: –55°C to 125°C.
Shock: MIL-STD-202, Method 213, Test Condition I
(100 G’s peak for 6 milliseconds).
Vibration: MIL-STD-202, Method 201 (10–55 Hz, 0.06 inches
total excursion).
Salt Spray: MIL-STD-202 Method 101, Test Condition B (48 hours).
Insulation Resistance (After Opening): MIL-STD-202, Method 302,
Test Condition B.
Resistance to Soldering Heat: (Axial Leaded Fuses):
MIL-STD-202, Method 210A, Test Condition B (260°C, 3 Seconds).
Thermal Shock: MIL-STD-202, Method 107,
Test Condition B (–65°C to 125°C).
Moisture Resistance: MIL-STD-202, Method 106
(90-98% RH, 65°C).
PEAK WITHSTAND CURRENT (lp): These fuses will withstand 50
repetitions of a double exponential impulse wave having peak currents
(lp) and peak voltages as listed.
PHYSICAL SPECIFICATIONS:
Materials: Glass Body, Nickel-Plated Brass Fuse Caps.
(Insulating sleeve option available).
Soldering parameters:
Wave solder — 500°F (260°C), 3 seconds Max.
Reflow solder — Not recommended.
Solderability: (Axial Leaded Fuses): MIL-STD-202,
Method 208.
PACKAGING SPECIFICATIONS: Tape and Reel pitch per
EIA-296;T1: 52.4mm (2.062") taped spacing; For 1,500 per reel, add
packaging suffix, DRT1. For 2,500 per reel, 5mm (.20") add packaging
pitch suffix, ERT1. Insulating sleeve option available.
* When ordering the 2AG Indicating Slo-Blo Fuse, an ‘S’ is
required after the catalog number.
Example:
-1A Indicating Slo-Blo® Fuse = 230 001S
NOTE: LF logo, series number, amperage rating, voltage rating, and UL and CSA logos are
stamped on the fuse caps.
