Part no. HSA50 2.4K Ohms
The HS is a range of extremely stable, high quality Wirewound Chassis Mount resistors capable of dissipating high power in a limited space with relatively low surface temperature. The power is rapidly dissipated as heat through the aluminium housing to a specified heatsink.
Each resistor is sealed in a ‘milspec’ type poly bag and labelled 10W 5259587 dated April 1976
Inside the bag it is further wrapped in corrugated card, inside that is another sealed bag and finally the part, marked…

Originally supplied to a large UK based ‘Milspec ‘ type Co. these came to us as part of a lot of surplus stock. As they have been in storage for many years we have classified them as ‘new other’, though they are stored with us still sealed in original packaging (dated April 1976 resistor dated 7421) and are in absolutely ‘as new pristine condition’.
We Purchase Surplus Stock!!!
If you or your company has items similar to the above, or indeed any electronic components surplus to requirements, please contact us with details as we are keen to increase our stock profile.
As many of our lines come in to us as surplus – sometimes from high end ‘Milspec’ type manufacturers we try to pass on our savings to our customers – often selling industrial grade or military spec components at a fraction of their original cost.
