Crystal oscillators are an indispensable frequency control component in today's technology. As electronic products continue to trend towards miniaturization, lightweight, and thin designs are at the forefront of the design wave. Crystal oscillators are widely used in wireless fields, smart home domains, robotics, security equipment, high-value intelligent devices, and digital fields.

The appearance of oscillators can be categorized into surface mount oscillators and through-hole oscillators. Through-hole oscillators are available in ceramic and quartz materials; surface mount oscillators further divide into active and passive types. Consequently, the oscillator packaging size is undoubtedly a favorable condition for identifying oscillator series models.

How can the packaging dimensions of oscillators be distinguished? For example, a 2520 package is composed of a crystal oscillator with a length of 2.5mm and a width of 2.0mm, abbreviated as a 2520 surface mount oscillator.

The oscillator series packaging is arranged from small to large as follows: 1610; 1612; 2012; 2016; 2060; 2520; 3080; 3215; 3225; 5032; 6035; 7050; 8045; 49S; 49SMD, etc. Below is a brief overview of the common and popular packaging sizes:

03, 2012 Surface Mount Crystal Oscillators

The 2012 SMD Crystal Oscillator is a very popular clock crystal in the current market. Unlike the expensive cost of the 1610, it also saves more space on the motherboard compared to the 3215 SMD Crystal Oscillator, and boasts excellent environmental heat resistance. TXC/China Taiwan Crystal Technology (Material Code: 9H03200028, 9H03200012); Japan NDK (NX2012SA series)

04. 2016 SMD Crystal Oscillators

In 2016, while the 2016 surface mount oscillator is not as slim as the 1612 version, it is more cost-effective. Brands include JINYX/Crystal, EPSON/Epson (passive oscillators FA-128 series), and Japan NDK (NX2016SA series).

05, 2520 SMD Crystal Oscillators

The 2520 surface mount crystal oscillator is a commonly used size in the market, featuring a miniaturized volume and low-cost consumption. The EPSON/Canon passive crystal oscillators (FA-20H series) offer a frequency range of 12MHz to 54MHz with selectable load capacitance from 6pF to ∞; The JINYX/crystal faring crystal oscillators also have a frequency range of 12MHz to 54MHz, with load capacitance options of 8pF, 10pF, 20pF, or specify.

06, 3225 SMD Crystal Oscillators

The 3225 surface mount crystal oscillator is a common sight in mainstream crystal oscillator packaging, with this form factor available from oscillators to temperature-compensated crystals.

A wide range of special crystal oscillators available: low frequency kHz, differential output, low jitter, programmable oscillators, ultra-high frequency oscillators, etc. Examples include: JINYX/Crystal Yuanxing crystals, EPSON/Epson TSX-3225 series, TXC Crystal 4P 3225, and more.

07, 5032 SMD Crystal Oscillator

Despite its relatively larger size, the 5032 is one of the mainstream oscillator package sizes, including JINYX's 5032 crystal oscillators.

08, 7050 SMD Crystal Oscillator

The 7050 crystal oscillator is a widely used size, offering a variety of characteristics for selection. It is particularly prevalent in the field of active crystal oscillators. For instance, the EPSON/Canon active crystal oscillator SG7050CAN series, JINYX Crystal Optics 7050, and SiTime MEMS programmable 7050, etc.
