Mystery Parts

Below are components and chips that I ran across many years ago. I had little or no idea what they did.

It didn’t take too long after the article was published for several thoughtful readers to provide the answer: Almost all of the mystery parts are either inductors and house labeled chips.



08

Labeled 08 or 80 (it depends on which way is up). Possible ferrite core with reddish brown magnet wire. Five leads, two on one side. A transformer?



Toko 12RF series inductor #457A-1017

Eight-sided surface-mount component with four leads. Labeled 1017.



Inductor 1000 microhenries 102GJ

Labeled 102 GJ=. Metal spool covered with gray plastic wrapper. Two leads. Likely an inductor.



152

Labeled .152. Blue plastic case with blue glue holding a coil. Two leads. Likely an inductor.



18K01

Labeled with 18K01 CPBD9944, 18K05 CPFF9939, 18K15 IK8844, 18K41 CPAT9913, 18K06 FKR9826. Black plastic DIPs, 14 pins. Second set of numbers on chip likely plant and date of manufacture.



18K25

Labeled with 18K25 CPCY9903, 18K27 FWR9814, 18K34 KK8847 ZUCRK. Black plastic DIPs, 16 pins. Second set of numbers on chip likely plant and date of manufacture.



18K35

Labeled with 18K35 CPFM9937, 18K43 CPPH9930, 18K44 CPHD9844, 18K45 IK8825. Black plastic DIPs, 16 pins. Second set of numbers on chip likely plant and date of manufacture.



18K56

Labeled with 18K56 CPAW9950. Black plastic DIP, 20 pins. Second set of numbers on chip likely plant and date of manufacture.



39M01

Labeled with 39M01 CPBF9942, 87K09 CPHE9950. Black plastic DIPs, 20 and 14 pins. Second set of numbers on chip likely plant and date of manufacture.



Full-bridge rectifier #21E08

Labeled 21E08 936C and + sign (polarized?). Black plastic round case with flat corner. Four leads. A rectifier?



600

Labeled 600 160 XK7H and TAIWAN. Orange-yellow, two leads. Self-resetting fuses?

80-pin surface-mount package SC390138FB

Labeled with SC390138FB 5184523TO7 LAH9938. Black plastic surface mount. 80 pins.



Ferrite core inductor?

Possible ferrite tube with wire core with ends insulated with clear plastic tubing. Airbrush bright yellow on one side. Two leads. Likely an inductor.



Red coil embedded in yellow plastic

Red coil embedded in yellow plastic. Two short leads. Likely an inductor.
