A Dk 10.2 laminate with a loss tangent below 0.0019: where RT6010LM earns its place, and when a related grade makes more sense.
Rogers RT6010LM is aimed squarely at high-frequency and microwave work. Its electrical behaviour, thermal stability and mechanical properties are what keep it in circulation across modern electronic hardware, and they are also what separate it from the general-purpose laminates it usually replaces. What follows is a look at the properties, the applications, and how it measures up against the materials it competes with.
Four groups of properties define the material. The specification table below summarises the headline figures; the sections after it explain what each one buys you.
| Property | Value |
|---|---|
| Dielectric constant (Dk) | ~10.2 |
| Dissipation factor (Df) | below 0.0019 |
| Thermal weight loss temperature | 300°C |
| Coefficient of thermal expansion | Relatively low |
| Machining | Laser cutting and precision machining |
| Chemical and moisture resistance | Good |
The loss figure is the reason most designers arrive here. Dielectric loss typically measures below 0.0019, which keeps signal attenuation low at high frequency and protects signal integrity. The dielectric constant sits around 10.2 — a high value that suits designs needing compact geometry and shorter electrical paths — and the electrical characteristics hold up across the high-frequency range rather than degrading as frequency climbs.
A thermal weight loss temperature of 300°C lets the material run reliably in hot environments, which is what puts it on the list for power amplifiers and RF modules. It also has a relatively low coefficient of thermal expansion, so electrical performance stays put through temperature swings and the signal distortion that comes with them stays small.
Tensile and compressive strength are high enough to survive the mechanical stress of complex circuit designs, and the material supports laser cutting and precision machining — useful when a layout needs dense routing and tight geometry instead of generous spacing.
Chemical resistance holds up against the reagents used in processing and in service, which suits industrial environments. Moisture resistance is good as well, so electrical performance is not compromised by humidity.
If the choice is still open, the RT/duroid 3210 and 3010 grades occupy the same high-Dk territory from a closely related platform, and the hydrocarbon RO3210 makes a different trade on processing. For the pure-PTFE comparison, the RO3010 versus RO6010 breakdown covers the same argument in more detail.
RT6010LM earns its place through a combination that is hard to assemble elsewhere: very low dielectric loss, a high and usable dielectric constant, thermal stability to 300°C, and mechanical and chemical resilience. In communication, radar, medical and automotive hardware it does the job without drama. Our Rogers 3000 series overview and the low-Dk 5880 parameter reference cover the opposite ends of the same decision.
Frequently Asked Questions
Around 10.2. The high value is what allows compact circuit geometry and shorter electrical paths, which is why it suits miniaturised RF hardware.
It is stronger on dielectric loss and thermal stability, and its higher dielectric constant supports more compact circuit designs.
FR-4 is cheaper, but its dielectric behaviour is unstable at high frequency. RT6010LM holds its electrical performance and thermal stability where FR-4 cannot.
