ISP Korea 5mm 100mA LEDs
A typical ISP 5mm 100mA LED.


International Systems Processing (ISP), 5mm 100mA white LED, part # 5W3(24)CA-H
Received and tested on 07-06-04
This looks like an ordinary 5mm round white LED in a water-clear epoxy package - until you connect it, anyway. These LEDs have a Vf (forward voltage) of 3.1 to 3.6 volts, and an If (forward current) of 100mA - or 0.1 amps.
The die (light-emitting chip) in this LED is square, and measures 24 mils (just over 1/3 the thickness of a US penny) on each side. Viewing angle is specified as 25°.

Since these LEDs are easy to confuse with regular 20mA 5mm LEDs in your parts bag, I suggest storing them in a marked bag, box, or other container, seperate from your 20mA 5mm LEDs.


Brightness measures 29,300mcd on a Meterman LM631 light meter.
Vf is 3.04 volts at 96mA. Forward current is 96mA (0.096 amps) on my Mid-Easterm variable voltage, current-clamping power supply that I used for this test, and that I will use for subsequent tests on this page.




International Systems Processing (ISP), 5mm 100mA blue LED, part # 5B3(24)CA
Received and tested on 07-06-04
This looks like an ordinary 5mm round blue LED in a water-clear epoxy package - until you hook it up, anyway. These LEDs have a Vf (forward voltage) of 3.1 to 3.6 volts, and an If (forward current) of 100mA - or 0.1 amps.
The die (light-emitting chip) in this LED is square, and measures 24 mils (just over 1/3 the thickness of a US penny) on each side.

The dominant wavelength (where you would point to on a color chart) appears to be right around 470nm, right where it ought to be.
Viewing angle is specified as 25°.

Since these LEDs are easy to confuse with regular 20mA 5mm LEDs in your parts bag, I suggest storing them in a marked bag, box, or other container, seperate from your 20mA 5mm LEDs.


Brightness measures 6,170mcd on a Meterman LM631 light meter.
Forward current is 96mA (0.096 amps).




International Systems Processing (ISP), 5mm 100mA green LED, part # 5G3(24)CA
Received 07-06-04, tested 07-07-04
This looks like an ordinary 5mm round green LED in a water-clear epoxy package - until you hook it up, anyway. These LEDs have a Vf (forward voltage) of 3.1 to 3.6 volts, and an If (forward current) of 100mA - or 0.1 amps.
The die (light-emitting chip) in this LED is square, and measures 24 mils (just over 1/3 the thickness of a US penny) on each side.

The dominant wavelength (where you would point to on a color chart) appears to be right around 525nm, right where it ought to be.
Viewing angle is specified as 25°.

Since these LEDs are easy to confuse with regular 20mA 5mm LEDs in your parts bag, I suggest storing them in a marked bag, box, or other container, seperate from your 20mA 5mm LEDs.


Brightness measures 16,500mcd on a Meterman LM631 light meter.
Forward current is 96mA (0.096 amps).




International Systems Processing (ISP), 5mm 100mA yellow LED, part # 5Y3(24)CA
Received 07-06-04, tested 07-10-04
This looks like an ordinary 5mm round yellow LED in a water-clear epoxy package - until you hook it up, anyway. These LEDs have a Vf (forward voltage) of 1.8 to 2.3 volts, and an If (forward current) of 100mA - or 0.1 amps.
The die (light-emitting chip) in this LED is square, and measures 24 mils (just over 1/3 the thickness of a US penny) on each side.

The dominant wavelength (where you would point to on a color chart) appears to be right around 587nm, right where it ought to be.
Viewing angle is specified as 25°.

Since these LEDs are easy to confuse with regular 20mA 5mm LEDs in your parts bag, I suggest storing them in a marked bag, box, or other container, seperate from your 20mA 5mm LEDs.


Light output is much less reddish than this photograph makes it appear.

Brightness measures 24,500mcd on a Meterman LM631 light meter.
These LEDs are only supposed to output 7,000mcd, so I may have gotten a particularly potent one.
Forward current is 96mA (0.096 amps).




International Systems Processing (ISP), 5mm 100mA yellow LED, part # 5R3(24)CA
Received 07-06-04, tested 07-11-04
This looks like an ordinary 5mm round red LED in a water-clear epoxy package - until you connect it, anyway. These LEDs have a Vf (forward voltage) of 1.8 to 2.3 volts, and an If (forward current) of 100mA - or 0.1 amps.
The die (light-emitting chip) in this LED is square, and measures 24 mils (just over 1/3 the thickness of a US penny) on each side.

The dominant wavelength (where you would point to on a color chart) appears to be right around 627nm, right about where it ought to be.
Viewing angle is specified as 25°.

Since these LEDs are easy to confuse with regular 20mA 5mm LEDs in your parts bag, I suggest storing them in a marked bag, box, or other container, seperate from your 20mA 5mm LEDs.


Brightness measures 16,200mcd on a Meterman LM631 light meter.
Forward current is 96mA (0.096 amps).



The blue and green LEDs have a 5nm range (465-470nm for the blue, 520-525nm for the green); the yellow and red LEDs have a 10nm range (580-590nm for the yellow, 620-630nm for the red).

I lost two of the LEDs (a blue one and a red one) while setting up for photo shoots and light measurements; Mr. Chang sent two of each, so I was able to complete the tests on them.
