36VDC CSF Self Control Protector Fuse Three Terminal Protection Element

Product Description

Lithium Lon Battery Notebook Power Tool Three Terminal SMD CSF Self Control Fuse For Cell Phone

CSF Introduction

Self Control Fuse (CSF) is a three-terminal protection element, which is mainly used for secondary protection of lithium-ion batteries such as laptops, tablets, digital cameras, POS machines and mobile phones.
 

CSF can provide overcurrent and overcharge protection for lithium batteries. When the lithium battery has overcurrent, the fuse will melt and cut off the current. Or when the battery is overcharged, the heater is activated. Because the heater is close to the fuse, the fuse is heated and melted. At this time, the battery charging current and the current flowing through the heater are cut off at the same time.
 

CSF can be installed by a placement machine and soldered by reflow soldering.

Features and Advantages

The structure is safe and reliable, and can withstand reflow soldering

Ceramic matrix, strong structure, high safe breaking capacity, and the use of high-temperature alloy, can
Suitable for reflow soldering with peak temperature below 255℃

The Main Parameters

1. Rated voltage: the highest voltage that the fuse can withstand in the process of cutting off the overload current;

2. Rated current: the working current that the fuse can carry;

3. Resistance: Mainly divided into fuse resistance and heating resistance;

4. Strings: cells, that is, the number of battery packs in series, generally 1-5 strings, corresponding to different types of products;

4. Breaking capacity: also known as short-circuit interception capacity, the maximum fault current that can be safely broken under rated voltage. Safe disconnection means that no phenomenon such as splashing, burning, explosion, etc. endangering surrounding elements, parts and even personal safety occurs in the disconnecting circuit;

5. Fusing characteristics: The fusing speed under a given overload condition is mainly divided into overcurrent (I-T Curve) and overvoltage (U-T Curve) characteristics.
