I've been looking for a 50 mm x 50 mm x16mm and 100 mm x 50 mm PCB mounted PCB shielding can with a lid. The only ones I've found that are close to these sizes are Parancea PFL6T and PFL9T. Parancea are OK, and it helps that they are local to me in the UK and available on RS and Farnell. But I'm just wondering if there is any other choice as they are a bit pricey. Any suggestions? Thanks.
