COMPONENT PARTS
Voltage Regulators 78L series
Small regulators with a 100mA output, TO-92
case. These are fixed voltage regulators with
very good regulation and ripple rejection (impor-
tant for audio, RF circuits).
Part No. 86-1105 type 78L05 @5V. regulator
Part No. 86-1112 type 78L12 @12V. regulator
LM317T 1.5 Amp
Variable Regulator I.C.
Typically used in one
amp variable power
supplies, will produce
as much as 1.5 amps
but be sure to
heatsink very well.
Many circuits in books
and magazines; used
in Datakits projects
tool
Part No. 86-1117 type LM317T I.C.
Hi Efficiency Red LED, 5pk.
Red LEDs do a good job at reduced
current, such as in the 5 to 10 mA
range; much brighter than other red
LEDs at standard 10 to 20mA current.
Unlike the highly directional super-
bright types, these are bright when
viewed from a wide angle, making
them excellent indicator lamps. Five
per pack.
Part No. 85-102 Red LED five pack
2 AMP Bridge Rectifier
BR805 2 AMP Bridge Rectifier.
In line SIP 4 lead package. This
package equals the four diodes
used in a full wave bridge circuit;
may also be used on battery powered cir-
cuits to protect against accidental reverse
polarity etc.
Part No. 86-1100 type BR805 bridge
Bright WHITE LED
LED, White Light This is an
exceptional bright LED with a
white light. If operated in its
rated range, it should never
burn out, ever. Current 10mA
to 20mA. Use for power indi-
cator or even for small, light-
weight and low current flash-
light, keyhole finder etc..
Millicandle power 7,000, 3.5-4.0 VDC.
Part No. 85-107 white LED
Popular Crystals
The package style is HC-
49/u. Most circuits will speci-
fy if Xtal needs to be series
or parallel. Parallel resonant
xtals are 20 pF loading
capacitance (not important
for series xtals). Generally,
series or parallel types are
specified by the circuit and
not interchangeable.

Part No.86-1444
TOROID (FERRITE)
BEADS
A package of a dozen small beads to
slip over wires for RF noise suppres-
sion. For wire sizes up to 20 gauge
insulated
Part No. 86-1570
SHIELDED TUNABLE RF COILS
