Silicon diode suitable for all circuit work including rectification.
Maximum current 1A.
MES Lamp Holder
A robust MES lamp-holder which can take normal torch bulbs of any voltage rating. The SX100-046 is the same holder but supplied with a 6V 60mA bulb.
SX100-045 MES Lamp Holder SX100-046 MES Lamp Holder with Bulb
LED Lamp Indicator
An innovative replacement for torch bulbs in circuit studies. The unit uses two parallel LEDs to give ultra long life.
Will work from 2V to 15V without damage and the low current (10mA) will greatly extend battery life. No bulbs to break in storage or by connection to the wrong supply.
LED (Red, Green and Yellow)
Mounted LED’s fitted with protection resistors an available in three different colours.
SX100-051 LED Red SX100-052 LED Green SX100-053 LED Yellow
A Mounted, light sensitive phototransistor for use in a variety of situations. The device can be incorporated into electronic sensor circuits for control applications or used as it is for investigations into its characteristics, i.e. how the output voltage varies with light intensity.
It has high sensitivity to visual wavelengths with a peak in the infra-red at about 850nm.
A mounted, light sensitive photodiode for use where less sensitivity than the phototransistor is required. It can be incorporated into electronic control circuits or investigated in terms of its characteristics whereby an interesting comparison can be made with the phototransistor .__
It has excellent response to visual wavelengths with a peak in the infra-red at about 850nm.
A light sensitive resistor for use as a sensor in electronic circuits. Resistance varies from > 1MΩ in the dark to about 200Ω in full sunlight.
Thermistor 5kΩ NTC
A bead thermistor with rapid response for use as a temperature sensor. Resistance varies from 15kΩ at 0 0 C to 300Ω at 100 0 C.
Typically 5kΩ at room temperature falling to 3kΩ when gripped between the fingers.
