Product Overview
Dale RH-10: 2K Ohm of Wirewound That Bolts Straight to Your Chassis
Condition
New, unused old stock. We hold this part in quantity, so the piece in the photos is representative of the group rather than the individual unit that gets picked for your order. On the photographed piece the gold-toned housing is clean and evenly colored with no dents, gouges, or scraped areas; the printed DALE oval and the RH-10, 2K ohm, 5%, 10W 7606 legend are sharp and fully legible; both flat leads are straight and free of bends or kinks, though their tinned faces read as dull and mottled rather than shiny; and the two mounting tabs are flat with clear, unburred holes. The photos cover the marked face, one end, and an angled side view, so the remaining faces are not visible here.

Product Overview
The RH-10 is the 10 watt size in Dale's RH line of aluminum-housed, chassis-mount wirewound power resistors, and this one is printed RH-10, 2K ohm, 5%, 10W with a four digit 7606 code following the ratings. The wirewound element sits inside a rectangular gold-toned housing that measures roughly 20 mm end to end against the millimeter rule in the photos, with a flat blade lead leaving each end and two mounting tabs placed on diagonally opposite corners instead of as a symmetric pair, so the hole pattern runs on the diagonal and is worth laying out before you drill. The housing is the point of the package: the 10 watt figure assumes the case is fastened to a heatsink or a metal chassis that can carry the heat away, and free air derates it. At 2,000 ohms this is a value that earns its keep as a bleeder across a filter bank, a standing load on a supply under test, or a current limit in a control circuit, and the wound element brings the steady behavior that construction is known for along with the parasitic inductance that comes with it.
Key Features
- Printed DALE oval logo and RH-10 series marking on the housing
- Resistance marked 2K ohm (2,000 ohms)
- Tolerance marked 5%
- Power marked 10W, rated with the case properly heatsinked
- Four digit 7606 code printed after the ratings
- Wirewound element in the RH series aluminum-housed chassis-mount package
- Rectangular gold-toned housing, approximately 20 mm long against the millimeter rule in the photos
- Two mounting tabs on diagonally opposite corners, holes clear and unburred
- Flat blade leads with a dull tinned finish, one from each end
- Unused new old stock, sold each
Applications
- Bench supply builder who wants a 2K bleeder across the filter bank so the capacitors do not sit charged after shutdown
- Restorer matching an original RH-10 in existing chassis holes, where the diagonal tab pattern has to line up with what is already drilled
- Test bench dummy or standing load bolted to an aluminum plate, sized in 10 watt steps
- Panel maintenance where a 2K current-limiting or bleed resistor has to mount to sheet metal rather than hang off a board
Frequently Asked Questions
Will it take the full 10 watts sitting in free air?
No. The 10 watt figure on an RH-style housing assumes the case is fastened down to a heatsink or a metal chassis that can move the heat away. Standing in open air the safe dissipation is considerably lower, so mount it to metal if you intend to work it hard.
What is the 7606 printed after the ratings?
It is a factory code printed on the housing after the value, tolerance, and wattage. Four digit codes in that position are commonly read as a date code, but we have not confirmed that reading for this part, so treat 7606 as a marking rather than a specification.
What is the maximum working voltage?
Not confirmed - verify against the datasheet before use. As arithmetic only, 10 watts into 2,000 ohms puts roughly 141 volts across the part at full rated dissipation, but the published series voltage limit is a separate number we cannot confirm here.
Does the wirewound inductance matter?
A wound element carries parasitic inductance, which is a non-issue for bleeders, standing loads, and current limiting, and something to account for in high frequency or fast pulse paths. If your circuit is sensitive to it, plan around it the way you would with any wirewound part.
Why buy two or three of these instead of a bag of fifty somewhere else?
Because a chassis repair usually needs one and a load bank needs a handful, not fifty. We hold this RH-10 in quantity, so you can take the exact count your build calls for and skip the drawer of leftovers you will never reach for again. Shipping is $8 flat rate, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Dale built the RH series to be bolted to metal and then forgotten about, and this one has spent a long stretch doing only the forgotten part. Give it a chassis to sink its heat into and it can get on with the rest of the job.
