Type 279
(No.P-279-E002)
Type 279 is a complete lead-free tantalum chip capacitor with open mechanism of built-in fuse type, which function is to
melt under large current and inhibit burning and smoking from capacitor.
FEATURES
1. Built-in fuse function to melt under large current and inhibit burning and smoking from capacitor.
2. This type is the most applicable for PC,
measurement instrument
,
semiconductor equipment, ATM, base station for
and cell phone.
3. This type is suitable for filtering of power supply with low impedance circuit and by-passing of random noise of source
line in ultra high speed logical circuit.
3. Soldering : 260°C for 10 seconds by reflow or flow soldering.
4. Various Case size lineup from 3528 to 7343H and 7257
5. Complete Lead-free with built-in fuse.

In order to expect the self alignment effect, it is recommended
that land width is almost the same size as terminal of
capacitor,and space between lands (c) nearly equal to the
space between terminals for appropriate soldering.
