[Repeater-Builder] MTR2000 Backplane Fuse
The fuse you are describing is available from www.mouser.com part # 576-0459005.ER . It is a SMF type fuse. you will find them also in the Motorola P110, GP300 and GP350 portable radios but they are rated at 4 amps for the portables. I hope this information helps. N5SLI
RE: [Repeater-Builder] MTR2000 Backplane Fuse
Pat, The part number you quoted is not the fuse for an MTR2000, and won't even fit the fuse holder. The correct fuse- there are two- is a Littelfuse type 453 NANO fuse rated at 5 amperes. Mouser carries this fuse as stock number 576-0453005.MR, for $ .67 each. The type 453 fuse CAN be surface mounted, but in the MTR2000, it plugs into a holder. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Pat Patterson Sent: Tuesday, December 30, 2008 10:55 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] MTR2000 Backplane Fuse The fuse you are describing is available from www.mouser.com part # 576-0459005.ER .

RE: [Repeater-Builder] MTR2000 Backplane Fuse
I took a close look at a spare Motorola MTR2000 fuse, part number 6583049X16, and can provide some additional data: The fuse is rectangular, with a square cross-section, and measures about 6.0mm by 2.6mm. It has a ceramic body, with silver-plated end caps. The legend IE5A is printed on one face. This fuse seems to be identical to Littelfuse (note the spelling) Series 453 Nano fuses. The data sheet is here: www.littelfuse.com/data/en/Data_Sheets/Littelfuse_Fuse_451_453.pdf 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Ray Brown Sent: Sunday, December 28, 2008 10:01 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] MTR2000 Backplane Fuse - Original Message - From: Chuck Kimball n0...@yahoo.com mailto:n0nhj%40yahoo.com To: Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com Sent: Sunday, December 28, 2008 5:45 AM Subject: [Repeater-Builder] MTR2000 Backplane Fuse Good Day Everyone: I'm looking for some info on the small fuses on the backplane of the MTR2000 repeaters. I've got a Instruction/Field Service Manual 68P81096E30-C, and can't find anything in there on the part number for the fuse. Apparently Motorola doesn't think those are field replaceable. ;) They are a 5A very small 1/8x1/8x1/4* fuse not much larger than a surface mount resistor - looks to be ceramic with metal ends. I've seen these once before, but don't know the name of that style to do any sort of a search on it. LittleFuse. I forget their exact part designation but several models of hospital beds uses them. I had never seen them before and unfortunately got them from the mfgr. of the beds because I needed some overnight and didn't have time to search. I got about 10 of each (they range from 0.5 to 7 amps @ 32 VDC) plus fuse holders for each one for $200. (sigh) I can't give any of the fuses away, but if anyone wants any surface- mounts for these fuses, I think I have about 30 of them that I could give away. :-) Anyway, Newark stocks them, too. :-) Ray, KBØSTN

RE: [Repeater-Builder] MTR2000 Backplane Fuse
Chuck, The answer is found on page 22, behind the Maintenance Troubleshooting tab, in the Replacing Fuses paragraph. Both fuses are 5 ampere, fast-blow, and are Motorola part number 6583049X16. The current price shown on MOL is $ 1.38 each. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Chuck Kimball Sent: Sunday, December 28, 2008 3:46 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] MTR2000 Backplane Fuse Good Day Everyone: I'm looking for some info on the small fuses on the backplane of the MTR2000 repeaters.
