469 Series - 1206 Size Slo-Blo^® Surface Mount Ceramic Fuse

This 469 Series is a 100% Lead-free, RoHS compliant and Halogen-free fuse series designed specifically to provide over-current protection to circuits that operate under high working ambient temperatures up to 150℃.

The general design ensures excellent temperature stability and performance reliability.

The high I²t values which is typical in the Littelfuse Ceramic fuse family, ensure high inrush current withstand capability.

Features

Operating Temperature from -55℃ to +150℃

100% Lead-free, RoHS compliant and Halogen-free

Suitable for both leaded and lead-free reflow/wave soldering

Applications

Automotive Electronics

LCD Displays

Servers

Notebook Computers

Printers

Scanners

Data Modems

Gaming Consoles

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	VDC (V)	32
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	1206 (3216)
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)	3.56
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)	0.052
Close Info	Interrupt Rating	60A@32VDC
Nominal Power Dissipation (W) Close Info	Nominal Power Dissipation (W)	0.944
Nominal Voltage Drop (mV) Close Info	Nominal Voltage Drop (mV)	0.236
Operating Temperature (deg C) Close Info	Operating Temperature (deg C)	-55�C - + 150�C
Moisture Sensitivity Level Close Info	Moisture Sensitivity Level	IPC/JEDEC J-STD-020C LEVEL 1
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	S
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 Body
