They are from the Panasonic 'EE' series.\u003c\/p\u003e\n\u003cp\u003eThese are used in various places such as modern TV backlight power supplies, Xenon photographic flash lamps etc, but are ideal for replacing the HT reservoir and filter capacitors in valve radios and amplifiers.\u003c\/p\u003e\n\u003cp\u003eI've used a 15uF plus a 33uF variation of these as a replacement for the dried-up old Hunts 16 + 32uF 'two in a can' type used either side of the smoothing inductor in the H.T. power supply of a 1950s Murphy A146CM valve radio as seen in the before and after photographs. (C38 and C39 on the schematic) There was also a 15uF HT decoupler in the radio console section which got the same treatment (C37). This cured an excessively loud mains hum on the set. If you have a valve radio which is otherwise working but has excessive hum, this is almost certainly what you want. The ripple current specification exceeds the 120mA of the old can type by a large margin, and the 450 VDC rating gives plenty of headroom for 300V D.C. HT working voltage. Operating endurance is given as 8000 hours at 105 centigrade. They would generally be used in more demanding situations such as modern 100kHz switching power supplies etc. and are rated as such.\u003c\/p\u003e\n\u003cp\u003eBuyers frequently question if these quite small caps can really do the job of the much bigger valve radio and amplifier caps that they are replacing. The answer is that electrolytic capacitor technology has moved on somewhat in the last fifty years, thanks to use in computer SMPSs and yes, they can. The Murphy 146 valve radio example shown in the pictures has been running daily hum-free for five years and I'm much happier having some decent modern caps in the HT PSU than some horrible old thing that might expire at any moment, spilling foul-smelling capacitor smoke into the room and setting the house on fire.\u003c\/p\u003e","brand":"Panasonic","offers":[{"title":"10uF \/ 1 Capacitor","offer_id":58776135893376,"sku":"PANA EE 10UF Q1","price":2.8,"currency_code":"GBP","in_stock":true},{"title":"10uF \/ 2 Capacitors","offer_id":58776135926144,"sku":"PANA EE 10UF Q2","price":4.9,"currency_code":"GBP","in_stock":true},{"title":"10uF \/ 3 Capacitors","offer_id":58776135958912,"sku":"PANA EE 10UF Q3","price":6.9,"currency_code":"GBP","in_stock":true},{"title":"10uF \/ 4 Capacitors","offer_id":58776135991680,"sku":"PANA EE 10UF Q4","price":8.9,"currency_code":"GBP","in_stock":true},{"title":"15uF \/ 1 Capacitor","offer_id":58776136024448,"sku":"PANA EE 15UF Q1","price":3.8,"currency_code":"GBP","in_stock":true},{"title":"15uF \/ 2 Capacitors","offer_id":58776136057216,"sku":"PANA EE 15UF Q2","price":6.9,"currency_code":"GBP","in_stock":true},{"title":"15uF \/ 3 Capacitors","offer_id":58776136089984,"sku":"PANA EE 15UF Q3","price":9.9,"currency_code":"GBP","in_stock":true},{"title":"15uF \/ 4 Capacitors","offer_id":58776136122752,"sku":"PANA EE 15UF Q4","price":11.9,"currency_code":"GBP","in_stock":true},{"title":"22uF \/ 1 Capacitor","offer_id":58776136155520,"sku":"PANA EE 22UF Q1","price":3.8,"currency_code":"GBP","in_stock":true},{"title":"22uF \/ 2 Capacitors","offer_id":58776136188288,"sku":"PANA EE 22UF Q2","price":6.9,"currency_code":"GBP","in_stock":true},{"title":"22uF \/ 3 Capacitors","offer_id":58776136221056,"sku":"PANA EE 22UF Q3","price":9.9,"currency_code":"GBP","in_stock":true},{"title":"22uF \/ 4 Capacitors","offer_id":58776136253824,"sku":"PANA EE 22UF Q4","price":11.9,"currency_code":"GBP","in_stock":true},{"title":"33uF \/ 1 Capacitor","offer_id":58776136286592,"sku":"PANA EE 33UF Q1","price":3.8,"currency_code":"GBP","in_stock":true},{"title":"33uF \/ 2 Capacitors","offer_id":58776136319360,"sku":"PANA EE 33UF Q2","price":6.9,"currency_code":"GBP","in_stock":true},{"title":"33uF \/ 3 Capacitors","offer_id":58776136352128,"sku":"PANA EE 33UF Q3","price":9.9,"currency_code":"GBP","in_stock":true},{"title":"33uF \/ 4 Capacitors","offer_id":58776136384896,"sku":"PANA EE 33UF Q4","price":11.9,"currency_code":"GBP","in_stock":true},{"title":"47uF \/ 1 Capacitor","offer_id":58776136417664,"sku":"PANA EE 47UF Q1","price":5.8,"currency_code":"GBP","in_stock":true},{"title":"47uF \/ 2 Capacitors","offer_id":58776136450432,"sku":"PANA EE 47UF Q2","price":9.9,"currency_code":"GBP","in_stock":true},{"title":"47uF \/ 3 Capacitors","offer_id":58776136483200,"sku":"PANA EE 47UF Q3","price":13.9,"currency_code":"GBP","in_stock":true},{"title":"47uF \/ 4 Capacitors","offer_id":58776136515968,"sku":"PANA EE 47UF Q4","price":16.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/group_5_top_s.jpg?v=1787681354"},{"product_id":"74ac-cmos-high-speed-fast-logic-gate-chips-dil-ic-texas-instruments","title":"74AC CMOS High Speed Fast Logic Gate Chips DIL IC Texas Instruments","description":"\u003cp\u003eThis is one item of new AC CMOS DIL IC.
