Product Overview
Motorola 06-124C33 - a file card pack of ten 220k Ohm, 1/8W carbon composition resistors with 10% tolerance. Vintage NOS stock from Motorola's Communications Division. Each card holds ten matched axial-lead resistors, bodies brown with Red-Red-Yellow-Silver color bands confirming 220k Ohm at 10% tolerance. Carbon composition construction - not carbon film - giving these the pulse-handling and low-inductance character that restorers and amp builders specifically seek out.
Key Features
- Resistance: 220k Ohm (220,000 Ohms)
- Power rating: 1/8W
- Tolerance: 10% (Silver band, EIA color code chart printed on card reverse)
- Type: Carbon composition - axial lead, brown body
- Quantity: 10 resistors per file card
- Color code: Red-Red-Yellow-Silver confirmed on physical units
- Card markings: 06-124C33 on tab, 54-84066A05 on reverse, PRINTED IN USA
- Unused NOS - unissued from original file card
Applications
- Desoldering a drifted or failed resistor from a vintage radio chassis and dropping in a period-correct carbon comp replacement to keep the restoration authentic
- Populating a new tube amplifier board where the builder wants the original carbon composition character rather than a modern film substitute
- Swapping a noisy resistor in a vintage guitar amplifier during a service call, matching the original component type for tone-sensitive customers
- Stocking a small repair shop's parts drawer with NOS Motorola values to handle legacy communications and consumer electronics without hunting individual units
- Breadboarding or prototyping with vintage components for retro computing and ham radio projects where era-correct parts matter
Frequently Asked Questions
Is this carbon composition or carbon film?
Carbon composition. The brown axial-lead body and the era of manufacture are consistent with carbon composition construction, and the research notes confirm this type. Carbon film resistors came into wider use later and have a different body profile.
Does the card contain 10 resistors, or is this priced per resistor?
The card contains 10 resistors. This listing is for the complete file card pack of 10 units as pictured.
What is the physical lead spacing or body length?
Not confirmed. Buyers fitting these into a specific PCB or chassis cutout should measure the original component before ordering if lead spacing is critical.
Are the resistors tested?
Evaluation: Visual inspection only. Function testing not performed. Components appear unissued and in NOS condition as described.
Some parts carry a little history with them. This card went from the Motorola line to a distributor shelf and never got used - which means whoever finally installs these gets the first-ever reading on a 220k that has been waiting decades for a circuit to call home.
