No. P-JHC-E006 DATE 2016-05 PRODUCTS DATA SHEET MICRO FUSE TYPE JHC SIZE 7.3x5.8mm UL. cUL approved File No.E170721 30A,40A,50A,60A RoHS compliant 〈Complete lead-free〉 MATSUO ELECTRIC Co., LTD.
(P-JHC-E006） Type JHC TYPE JHC High Current Micro Fuse is designed for the purpose of external short circuit protection of the lithium ion battery of medium sizes, such as a power tool and an electric assistant bicycle. Though it was a surface mount type, it was small and realized high current rating, because a fuse element and a terminal adopt the structure of one. Furthermore perfectly compliant to Lead-free makes environment friendly design. FEATURES 1.

Determine the rated value of the micro fuse, and select the micro fuse for your circuit. If you select the micro fuse , safety of your circuit can be ensured. How to determine the rated value of the micro fuse is described below: ■Flow for fuse selection 1. Measurement of circuit values using actual device Measure the circuit values, such as operating current of the circuit. 2.
Calculation using Formula 1 : Rated current ≥ 30/(0.90×0.94) = 35.5A The above calculation result shows that the fuse with rated current of 35.5A or more should be selected for this circuit. Type JHC, with rated current of 50 A and 40A can be selected. 3. Calculation from overload current 3–1 Measurement of overload current Using oscilloscope or equivalents, measure overload current that needs to break circuit.
(generally 100,000 times) ②Obtain load ratio from Pulse resistance characteristics. (Fig. D) Example : 100,000 times is required against inrush current applied. The load ratio is 35% or less from Fig. D.

Standard I2t of fuse > (I2t of inrush current/load ratio) ...
