After leaving for 24 hours or more in 25±2°C, it measures by 4 wire measuring methods using the direct-current terminal current of 10mA or less (0.1 or

less Vdcs).

#Glass-Epoxy PC board

#Standard land dimension

Rating Value

Temperature range with maximum voltage applied to PTC.

After leaving for 24 hrs. or more in 25°C, it measures by 4 wire

measuring methods using the direct-current terminal current of

10mA or less (0.1 or less Vdcs).

We apply 120% of the maximum operating voltage to PTC by

raising gradually for 180±5 secs. at 25°C. (A protective resistor

is to be connected in series, and the inrush current through

PTC must be limited below maximum rated value.)

EIAJ ET-7403 term 9

Soldered PTC to PCB and add the force of 5.0N in the direction

as shown below.

JIS C 5102 term 8.2

Vibrate for 2 hrs. in each of 3 mutually perpendicular planes for

a total of 6 hrs.

JIS C 5102 term 8.4

60±3°C leave for 1000±10 hrs.

-10±3°C leave for 1000±10 hrs.

60±2°C, 90-95%RH leave for 500±4 hrs.

JIS C 5102 term 9.3

Times: 5 cycles

60±3°C (in air), PTC is applied maximum operating voltage for

1.5 hrs. on and 0.5 hrs. off. This cycle is repeated for 500±10 hrs.

Soldered PTC to PCB

Vibration: A 10-55-10Hz (1 min.)

Width: 1.5mm

Solder: Sn 63%/Pb 37% (or 60/40%)

Solder temp: 230±5°C

Soaking time: 3±0.5 secs.

Soaking position: Until a whole electrode is soaked.

Solder: Sn 63%/Pb 37% (or 60/40%)

Flax: Solder paste containing less than 0.2wt% of chlorine.

Preheating: 150±5°C 3 mins.

Peak temp.: 260±5°C 10±5 secs. (reflow)

PCB: Glass Epoxy PCB (JIS C 6484)
