    I need a cpl. of inductors for my Roland Cj-500 main board,, I have not idea where to buy them or even what to look for since there are not much markings on it,, other then 181 on top and 125°c mark on the side. One located on L1 the other on L2 board markings. Enclosed is a picture of it.. if someone familiar with this item, please message me...

    "L" always refers to an inductor in circuit schematics and boards. I found this part# CL02BE181 in the service manual. Hope it helps.

    Nice find!

    If that doesn't work, you could always de-solder it and bring it in to an electronic component shop. If they can't identify it by sight, they should be able to measure the inductance for you, then fix you up with a matching product.

    Rafael's right though; with the "L" designation, it's definitely an inductor.

    Actually, one more bit of information. The 181 stamped on the top should be the μH (micro Henris) rating. 181 would signify that this inductor operates at 180μH. Couple that with the fact that it's rated for 125°C, and that it looks like a fixed, shielded inductor, any guy at a components counter should be able to help you.

    Thank guys,, great information for someone like me with little understanding about electrical circuit components, I should be able to find this product since now I know what it is and what to look for online. Just one more thing,, should I look for specific voltage as well?
