Product Overview
The 2N2484 is a low-noise NPN amplifier type built for low-level work from direct current up to around 100 MHz. This page is one piece rather than a sample from a bin: a TO-18 metal can with gold-colored leads, the can printed 2N2484 with HONGKONG below it, photographed twice held between fingers against a white granular backdrop and once lying loose on a light crinkled one. Stock on this part number is one, and it ships as the transistor in these photographs.
Key Features
- Type: NPN silicon low-noise amplifier transistor
- Collector-emitter and collector-base voltage: 60 V each (V_CEO and V_CBO, per published 2N2484 data)
- Emitter-base voltage: 6 V, per published 2N2484 data
- Collector current: 50 mA, per published 2N2484 data
- Power dissipation: published sources give between 360 mW and 500 mW, so we state the spread rather than pick a figure
- Current gain: minimum h_FE quoted as 225 to 250 depending on the source, per published data
- Transition frequency: about 100 MHz, per published data and this listing's own existing copy
- Package: TO-18 metal can, through-hole, gold-colored leads as photographed
- Marking on this can: 2N2484, with HONGKONG below it
- Verify against the published 2N2484 data before designing in.
Applications
- Low-noise front ends in instrumentation and audio preamplifiers
- Low-level direct current amplification where drift and noise matter
- Small-signal stages up to around 100 MHz
- Repair of legacy metal-can transistor positions
Frequently Asked Questions
How many should I order?
One, because one is what there is. Stock on this part number is a single piece, so this is not a representative photograph of a bin: it is the transistor in the pictures and it ships as shown, marking and all. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
What can you tell me about this exact can?
What is legible, and no more. The can reads 2N2484 with HONGKONG below it. Characters sit ahead of and after the type number, but they run off the curve of the can and are not fully legible in these frames, so we do not quote them. The leads are gold-colored. How many leads this can has is not resolvable from any of the three photographs, so this page states no lead count; ask and we will pick the piece up off the shelf and tell you before you order.
One transistor, gold-legged, with HONGKONG printed on a can the size of a pencil eraser.
